The car had a stumble before, but that was a known fuel problem that the previous owner had warned us about (hence the change to the cell etc, and it cured the left-hand corner problems). The car is carb'd, but we run a Holley pump with about 100x the capacity we need, and regulate it down to 3.5 psi. And we didn't mess with that little screw. Bad things happen when people mess with that little screw. I'll try the rev'ing in neutral test tomorrrow at the track, and will rig up the fuel pressure gage when I do it. I've done a little too much "neighbor testing" lately to try it tonight. And the secondarys open- I've tested them with a MityVac, and made sure there was vacuum on that line.
